As I write this article, 49 people have been confirmed dead after a mass shooting at a popular nightclub in Orlando, FL, with an additional 53 reported injured. In recent times, similar shootings have occurred with frightening regularity. In 2015 alone, we can recount San Bernadino, California; Colorado Springs, Colorado; Roseburg, Oregon; Chattanooga, Tennessee; and Charleston, North Carolina. People are being killed in unprecedented numbers, yet we have a poor understanding of the disease that is taking their lives. Gun violence is now a concerning public health issue and it begs the question: where are the patient advocates?
